jwe,
How do you want to handle patterns in the code such as this from balance.cc?
-- balance.cc:107 --
if (nn != args(0).columns ())
{
gripe_square_matrix_required ("balance");
return retval;
}
-- End Code --
The gripe() function in question is just a trivial wrapper around error.
-- gripes.cc:81 --
gripe_square_matrix_required (const char *name)
{
error ("%s: argument must be a square matrix", name);
}
-- End Code --
Not all of the gripe functions necessarily use error. Some of them take an
optional third argument (iserror) that determines whether a warning or an
error is issued. This complicates things, but it still seems like we could
mark at least a subset of the gripe routines with GCC_ATTR_NORETURN.
